6 Claims. 1

This invention relates to marking tools. Among the objects of theinventionis to provide a tool for marking upon a strip and for punchingholes in the strip without removing the strip from the tool.

Another object of the invention is to provide a hand-operable instrumenthavingpivoted handles and marking and punching devices which areoperable through force derived by the movement ofthe handles and whereinmeans are provided for selectively marking or punching a hole in a stripby eliminating either the marking device or the punching device fromfunctional co-operation with the handles so that either a marking orpunching operation may be performed when the handles of the instrumentare moved with respect to each other.

In its commercial application, lthe invention is vconcerned withsupplementing the markingtool described in United States Patent2,275,670 to extend the usefulness of 'that too-l. In the tool of thepatent means are provided for feeding a metallic strip step by step 'ascharacters are successively embossed lon the strip. The marked stripobtained by the use of the tool is commonly 'employed for identificationpurposes, but when it is necessary toprovide holes in the strip t enableits attachment to an object, it is necessary to use a separate tool forpunching the holes. The present invention provides punching mechanism incombination with the marking device of the tool whereby holes may bepunched in the strip of metal, as desired.

'Other features vand 'advantages of the present invention will bedescribed in the accompanying speciiication and claims with reference tothe drawings in which a machine embodying the principle of my inventionis illustrated.

'In the drawings,

Fig. 1 is a plan of the tool showing my improvement;

Fig. 2'is a side view ofthe tool shown Vin Fig. l;

Fig. 3is an end view of the tool shown in Figs, l and2;

Fig. 4 is a longitudinal section on line 4-4 of acover :I5 whichzis'pivotally attached tothe body .member by a screwI I6. Ari-operatinghandle I'l ,is pivotally connected to the body member IG by means of apivot pin I 8 which extends through a narrowed portion I9 of handle I1and through lugs 2i] and 2| lwhich are integral portions o'f body memberI0.

The portion of the bodyrmember Hl Vfacinghan dle Il is hollowed between'.anges v22 and 23 which extend the greater 'length of member Ill. Theilanges are grooved at 214 and 25, Fig. 7, for guiding the strip I4 asit is advanced from the vmagazine to the frontend of the tool.

The strip of metal I4 is fed'forwardly'between a resilient roll 26 and abracket v21 which is-attached to the body member Il] by means of fascrew 28. Roll 26 is tightly mounted on a shaft`29 which carries a thumbwheel 3l! and a ratchet wheel 3 I. Ratchet wheel -3 I 'is ynormallyengaged by a pawl 32 which is resiliently pressed into contact with theratchet wheel by means of atorsion spring -33 having one end 34 engagingthe back edge of the pawl and its other end 35 anchored in handle I1.rPhe torsion Yspring is coiled about a pin 36 which is threaded at itsendend engaged in handle I'l. The construction and arrangement is suchthat when handle I1 is advanced towards bodymember I!) as the handlepivots about pin I8, pawl v3.2 will slip idly over a tooth of ratchetWheel 3|. Upon release of the Yhandle I7, pawl 32 will actuate ratchetwheel 3l and feed roll 26 one step and cause advancement of strip I4towards the front end o-f the tool. The en'ds of shaft 29 are journalledin outside anges 31 and 38 of member-I I).

Pawl 32 is'provided' with an ear 39 by which the pawl may be heldretracted and away from engagement with the ratchet Wheel. When the pawlis disengaged from the ratchet wheel by ringer pressure `on ear 3B, thestrip I4 maybe moved forwardly and rearwardly along the tool byoperating thumb wheel 30. The advantage of this control over theposition of the strip will appear hereinafter.

A spring 40, Fig. 4, normally holds handle I1 away from body member III.This spring'is located over a projection 4I on handle I'l and'over aprojection 42 which extends downwardly from a shelf-like plate43. Plate43 is iixedly attached to body member IIJ by screws 44 and 45, Fig. 4,and by a central pivot screw 45, Fig. 6. Screws 44 and 45 are engaged inflange 23 of body member IU and pivot screw 46 is supported from a ledge41 which is integral with and extends laterally from the body member.

The maximum distance of separation of handle I"I and body member II] isattained through a link 48. This link is pivotally supportedonshaft 2,9and has an elongated opening 49 at its lower end which is engaged by theshank of screw 35 carried by .handle Il'.

The ledge 4l and plate 43 serve as -a rigid support for the turntableembossing unit. As

shown in Fig. 6, this unit includes a top plate 50 with a series ofintaglio dies 5I arranged circularly at its under surface and a exibledisk 52 having radial slots whereby flexible teeth 53 are provided whichcan be bent independently of each other. These teeth have raised dieportions 54 at their free ends which selectively cooperate with theintaglio dies during an embossing operation. A spacing plate 55separates the upper and lower die plates and is joined thereto by rivets56, Fig. 6, so as to form a single unit rotatable about screw 46. Theupper die plate 50 has on its upper surface a series of characters 51,Fig. 1, for aid in selecting any pair of character dies. The edge of theupper die plate has notches 58 equal in number to the number ofcharacters. The various embossing positions of the embossing unit aredetermined by a detent spring 59 which is adapted to serially engage thenotches as the unit is rotated for selection of a marking character.This detent spring is fastened to the body member I by means of a screw60 and serves to locate the embossing unit ln any selected position.Ledge 41 is provided with an index 6I, Fig. l, pointing towards anopening 62 through which may be viewed the character of the embossingunit which is in position for embossing the strip I4.

The embossing operation is performed by the forceful application of aplunger 64 to the under die 54 of the pair of dies which is in embossingposition, Fig. 6. The top of the plunger has a tapered anvil whichengages the under side of a die 54. This plunger is mounted forreciprocation in a sleeve 65 depending from plate 43.

Plunger 64 is resiliently held in retracted position by a forked spring66, which engages opposite ends of a pin 68 extending through theplunger. The pin is guided in slots 69 and 10 at either side of thesleeve.V When the operating parts of the tool are arranged to perform apunching operation, the plunger is supported in its sleeve by a secondforked spring B1. Forked springs 66 and 61 are bent upwardly and haveholes at their supported ends which are engaged by projection 42 at thelowerside of plate 43. The supported ends of the springs are heldagainst plate 43 by spring 40. The forked ends of the springs overlieand underlie pin 68 so .that the lower spring supports the plunger andthe upper spring restores the plunger to its normal position, Figs. 4and 6, following an embossing operation.

A displaceable element 1I underlies the lower end of plunger 64 wherebythe movement of the handle I1 towards the body member is transmitted tothe plunger during an embossing operation. Whereas an integralprojection from handle I1 may be used to engage the lower surface of thedisplaceable element 1I, I prefer to employ an adjustable screw 12mounted in a threaded bore in the handle. This screw serves as aprojection from handle I1. The screw is fixed by a locking screw 13after its position has been determined.

Displaceable element 1I is xedly mounted upon a rod 14 which is slidablethrough openings in the side walls of handle I1. The position of the rodcontrols and determines whether an embossing or punching operation willoccur when the handles are pivoted with respect to each other. A spring15, Fig. 5, normally holds the rod in such a position as to locate thedis.- placeable element between screw 12 and the lower end of plunger64. So long as the displaceable element is held in this position,plunger 64 will be actuated to cause an embossing operation each timethe handles of the instrument are squeezed together. By displacing rod14 axially of itself, element 1I is moved from its normal position to alocation 11, Fig. 6, so that if the instrument handles are operated withthe element so displaced, there will be no pressure brought to bear uponthe lower end of the plunger 64 and no embossing operation will takeplace. The displaceable element 1I has a rounded nose or wedge so thatit will readily enter between the plunger and screw 12 when it returnsto its normal position under the action of spring 15 when pressure uponrod 14 is released.

Upon each operation of the handles towards each other, with wedge 1Iunderlying the plunger, selected characters will be embossed upon thestrip and successive embossings will be applied to the strip in spacedrelation along the strip. As previously explained, the strip is advancedon each release of the handle I1.

The forward end of the strip may be observed through windows 18, Figs. 1and 4. The strip may be punched anywhere along its length by locatingthe place on the strip for perforation between punch and die 6I whichare located at the front end of the body member I0.

The punch is mounted in a vertical bore in the nose 82 of body memberIIl immediately above the steel rod 8l in which the die hole is drilled.This steel rod extends between lugs 20 and 2I which depend from bodymember I0. The punch is normally held in an elevated position by aspring 83 having its lower end fastened to the memberl I6 by a screw 84.The upper end 85 of the spring is forked for engaging a groove 86 at theupper end of the punch.

The punch is operated through a lever 88 which is, pivotally connectedby a screw 89 to the body member I0 and has a lateral projection 90overlying the upper end of the punch. This lever has extending laterallytherefrom a pin 9 I, Fig. 4, which abuts lug 2| for limiting theclockwise movement of the lever about pivot screw 89, Fig. 4. The reararm 92 of the lever is shaped to extend just above the hole in the wallof handle I1 in which rod 14 is supported, so that the end of the rodmay be projected outwardly from the wall whenever the handles are inopen position, as shown in Fig. 4, but not after movement of the handleshas commenced.

Lever 88 may -be swung in a. counterclockwise direction, Fig. 4, onlywhen rod 14 is moved axially of itself and its end 93 projects beyondthe side wall of handle I1, but when the rod is retracted and thehandles are squeezed together, the lever will not be moved. It follows,therefore, that during embossing operations, the punch will not beoperated, and that when it is desired to punch a hole, rod 14 must bedisplaced axially by pressure upon its end 16 whereby the other end 93of the rod is disposed beneath lthe lower edge of lever 88 so that uponmovement of handle I1, force will be transmitted to the lever throughthe rod and' a punching operation will occur. Spring 83 serves toelevate the punch to its normal position and rotate lever 88 clockwise,Fig. 4, as

:the handles are separated following a punching operation.

The strip will not be advanced during the punching of a hole, but willbe advanced one step following the punching operation when Ahandle I1moves away from body member I0 and the feed roll is actuated by pawl 32and ratchet wheel 3l. However, any desired location of a hole in thestrip lll may be had by moving the strip in either'directionunder thecontrol of the thumb wheel 30, but when retracting the strip into thetool it is necessary to release pawl 32 from engagement with ratchetwheel 3l. It likewise is possible to sever the strip at any desiredpoint by similarly controlling the position of the strip with respect tothe tool.

The shearing means includes a iixed shear plate Elfi, which is fastenedto the nose 92 of the body member by means 0f screws 95 and 96, and alever 91 bearing a knife 93 which is pivotally mounted upon screw 95 andmay be brought to bear against the lower side of the strip i4 forshearing the strip between the blade and the shear plate. Normally theblade is disposed away from the shear plate, as shown in Fig. 3, so asto permit the free passage of strip I4 from the end of the tool.
